Answers

Answer 1

In a class, there are 18 girls and 14 boys. If the teacher selects two students at random to attend a party with the principal, the probability that the two students are the same sex is 0.49.

For getting, the total number of students in the class. There are 18 girls and 14 boys.

Therefore, the total number of students = 18 + 14 = 32

Find the number of ways of choosing two students from 32 students.

This can be calculated by using the combination formula: ⁿC₂ = n! / ((n - r)! r!).

Here, n = 32 (total number of students), and r = 2 (number of students that we have to select).

ⁿC₂ = 32C₂ ⇒ 32! / ((32 - 2)! 2!) ⇒ (32 × 31) / (2 × 1) ⇒ 496

Find the number of ways of selecting two students of the same sex.

The number of ways of selecting two girls = ¹⁸C₂ ⇒ 153

The number of ways of selecting two boys = 14C₂ ⇒ 91

Find the probability of selecting two students of the same sex.

Total number of ways of selecting two students of the same sex = 153 + 91 = 244

Probability of selecting two students of the same sex = (Number of ways of selecting two students of the same sex) / (Total number of ways of selecting two students)

⇒ 244 / 496 ⇒ 0.49

Therefore, the probability that the two students are the same sex is 0.49.

circular cloud of poison gas from a factory explosion is expanding so that hours after the explosion the radius of the cloud is meters. how fast is the area of the cloud increasing hours after the explosion?

Answers

The rate at which the area of the cloud is increasing is equal to the product of the rate of expansion and the square of the radius of the cloud.

Therefore, the rate at which the area of the cloud is increasing is equal to the product of the rate of expansion and the radius of the cloud. The rate of expansion can be calculated using the equation . Therefore, the rate at which the area of the cloud is increasing can be calculated as .

The area of a circle is determined by the square of its radius. Thus, when the radius of the cloud is expanding at a rate, the area of the cloud is increasing at a rate that is proportional to the square of its radius.

Therefore, in order to calculate the rate at which the area of the cloud is increasing, we must calculate the rate of expansion of the radius of the cloud and then multiply it by the square of the radius of the cloud. To calculate the rate of expansion of the radius of the cloud, we can use the equation .

After we have calculated the rate of expansion, we can then multiply it by the square of the radius of the cloud to calculate the rate at which the area of the cloud is increasing.

Answers

By answering the presented question, we may conclude that Therefore, trapezium the height of the trapezoid is 71.5 centimeters.

What is trapezium?

A trapezium is a two-dimensional geometric figure with four sides, one pair parallel to the other. It is also called as a trapezium in certain locations. The parallel sides are known as bases, whereas the non-parallel sides are known as legs. The distance between the two bases is the trapezoid's height or altitude. The area of a trapezium is given by A = 0.5 * (b1 + b2) * h, where b1 and b2 are the lengths of the two bases and h is the height.

To find the height of the trapezoid,

Area = (b1 + b2) × h / 2

h = 2 × Area / (b1 + b2)

h = 2 × 7722 / (131 + 85)

h = 2 × 7722 / 216

h = 71.5

Therefore, the height of the trapezoid is 71.5 centimeters.

Juan Carlos claims that he cannot graph a point at (- 3.25, 6.5) because his coordinate plane only has whole numbers on the axis.

Answers

The intersection of two numerical axes creates a two-dimensional plane known as a coordinate plane. The x-axis, which is a horizontal number axis, and the y-axis, which is a vertical number axis, are two different types of number axes.

The French mathematician René Descartes enhanced the coordinate plane that had been created centuries earlier. The system is occasionally referred to as the Cartesian coordinate system in his honor. You can doodle points and lines on coordinate planes. With the aid of this method, we may generate and communicate algebraic concepts as well as visually express algebraic relations.

The coordinate plane has a horizontal axis, a vertical axis, and a right angle where numerous straight lines intersect. In a coordinate plane, the horizontal axis is represented by the x axis. The vertical axis is referred to as the y-axis. The origin is the location where the two axes meet. On both the x- and y-axes, the origin is at 0.

As ordered pairs, positions on the coordinate plane are described.

By connecting the position of the point along the x-axis (the first value in the ordered pair) and the y-axis (the second value in the ordered pair), an ordered pair reveals the location of the point.

The first value in an ordered pair, like (x, y), is referred to as the x coordinate, and the second value is referred to as the y coordinate. The x coordinates are presented before the y coordinates; take note of this. The ordered pair of the origin is represented as (0, 0), since it has an ordinate and abscissa of 0.

The function f(x) = |-x| is an even function, the equation of the parabola that has vertex at (2, 7) and passes through the point (-1, 3) is y = (-4/9)(x - 2)^2 + 7.

What is an odd or even function?

An odd function is a function that satisfies the property f(-x) = -f(x) for all values of x in the function's domain. Geometrically, this means that an odd function is symmetric about the origin.

To determine if the function f(x) = |-x| is an odd or even function, we can use the definition of odd and even functions.

First, let's check if f(-x) = f(x) for all values of x in the domain of the function:

f(-x) = |-(-x)| = |x|

f(x) = |-x|

Since |x| is equal to |-x| for all values of x, we have f(-x) = f(x) for all x in the domain. This means that f(x) is an even function.

2. There are different methods to find the equation of a parabola given its vertex and another point on the curve. One possible way is to use the standard form of the equation of a parabola:

y = a(x - h)^2 + k

where (h, k) is the vertex and a is a constant that determines the shape and orientation of the parabola.

To find a, we can use the fact that the point (-1, 3) lies on the parabola:

3 = a(-1 - 2)^2 + 7

3 = 9a + 7

9a = -4

a = -4/9

Substituting this value of a and the vertex (h, k) = (2, 7) into the equation, we get:

y = (-4/9)(x - 2)^2 + 7

Therefore, the equation of the parabola that has its vertex at (2, 7) and passes through the point (-1, 3) is:

y = (-4/9)(x - 2)^2 + 7

3. To determine whether the function f(x) = 25 - x^3 is even, odd, or neither, we need to find f(-x) and -f(x):

f(-x) = 25 - (-x)^3 = 25 + x^3

-f(x) = -(25 - x^3) = -25 + x^3

Now, let's compare f(-x) and -f(x):

f(-x) = 25 + x^3 ≠ f(x) and f(-x) ≠ -f(x)

-f(x) = -25 + x^3 ≠ f(x) and -f(x) ≠ -f(x)

Since neither f(-x) = f(x) nor f(-x) = -f(x) hold for all x in the domain of f, the function f(x) = 25 - x^3 is neither even nor odd.

4. To determine whether the function f(x) = 72 - x^4 is even, odd, or neither, we need to find f(-x) and -f(x):

f(-x) = 72 - (-x)^4 = 72 - x^4

-f(x) = -(72 - x^4) = -72 + x^4

Now, let's compare f(-x) and -f(x):

f(-x) = 72 - x^4 = f(x)

-f(x) = -72 + x^4 ≠ f(x) and -f(x) ≠ -f(x)

Since f(-x) = f(x) for all x in the domain of f, the function f(x) = 72 - x^4 is even. This means that its graph is symmetric with respect to the y-axis.

Answer:

y = 3x - 7

Step-by-step explanation:

We can use the two-point form formula to find the equation of a line that passes through two given points (x1, y1) and (x2, y2):

y - y1 = (y2 - y1) / (x2 - x1) * (x - x1)

where (x1, y1) and (x2, y2) are the two points and (x, y) represents any point on the line.

Using the given points, we have:

x1 = 1, y1 = 10

x2 = -4, y2 = -5

Substituting these values into the formula, we get:

y - 10 = (-5 - 10) / (-4 - 1) * (x - 1)

Simplifying the equation, we have:

y - 10 = 3(x - 1)

Expanding and rearranging, we get:

y = 3x - 7

Answers

The answer of the given question based on the graph could be used to determine the variance levels that would result in a package of vegetables is histogram.

What is Histogram?

A histogram is a bar graph-like representation of data that groups data into ranges, called bins, and displays the frequency of data within each bin. In this case, the x-axis of the histogram would represent the weight of the vegetable packages, and the y-axis would represent the frequency of packages that fall within each weight bin.

To determine variance levels that would result in package of vegetables being rejected because of its weight, histogram would need to be constructed based on tolerance level of company. The histogram would show distribution of package weights, and any packages that fall outside of the acceptable weight range would be considered rejected. By analyzing the histogram, the company could determine the variance levels that would result in package rejection and make necessary adjustments to their production process.

Company revenue quadratic function.

Angel

The revenue, in billions of dollars, for a company in the year 2002 was $2.7 billion. One year later, in 2003, the revenue had risen to $3.4 billion. In 2005, the revenue climbed to $3.9 billion, before falling to $2.7 billion in 2008. The revenue, r, in billions of dollars, for the company, is a quadratic function of the number of years since 2002, x. what is the vertex of the function?

To find the quadratic function that represents the revenue of the company as a function of the number of years since 2002, we can use the vertex form of a quadratic function:

r(x) = a(x - h)^2 + k

where a is the coefficient of the quadratic term, h is the x-coordinate of the vertex, and k is the y-coordinate of the vertex.

We can use the given revenue values to set up a system of three equations:

2.7 = a(0 - h)^2 + k

3.4 = a(1 - h)^2 + k

2.7 = a(6 - h)^2 + k

Subtracting the first equation from the second, and the first equation from the third, we get:

0.7 = a(1 - h)^2

0 = a(6 - h)^2

Since a cannot be zero (otherwise we wouldn't have a quadratic function), we can divide the second equation by the first to get:

6 - h = 10

which gives us h = -4.

Substituting h = -4 into the first equation, we get:

2.7 = a(0 - (-4))^2 + k

2.7 = 16a + k

Substituting the revenue value for 2005, we get:

3.9 = a(3 - (-4))^2 + k

3.9 = 49a + k

Solving for a and k, we get:

a = -0.1

k = 4.3

Therefore, the quadratic function that represents the revenue of the company as a function of the number of years since 2002 is:

r(x) = -0.1(x + 4)^2 + 4.3

The vertex of this function is at (-4, 4.3).

What is the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101?

We can notice that the sequence alternates between adding an odd number and subtracting an even number. The first term is 3, which is odd, so the sequence starts by adding an odd number. The second term is -4, which is even, so the sequence then subtracts an even number. This pattern continues, so the sum of the sequence can be written as:

3 - 4 + 5 - 6 + ... + 101

We can group the terms into pairs:

(3 - 4) + (5 - 6) + ... + (99 - 100) + 101

Each pair of terms adds up to -1, so we can simplify the expression to:

-1 -1 -1 ... -1 + 101

where there are 50 pairs of -1's. The sum of 50 -1's is -50, so the sum of the sequence is:

-50 + 101 = 51

Therefore, the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101 is 51.

What is 12 7/8 - 56/17?

To subtract mixed numbers like 12 7/8, we first need to convert it to an improper fraction. We can do this by multiplying the whole number by the denominator of the fraction, and adding the result to the numerator. This gives us:

12 7/8 = (12 × 8 + 7)/8 = 103/8

Now we can subtract 56/17 from 103/8. To do this, we need to find a common denominator for the two fractions. The least common multiple of 8 and 17 is 136, so we can rewrite the fractions with this denominator:

103/8 = (103/8) × (17/17) = 1751/136

56/17 = (56/17) × (8/8) = 448/136

Now we can subtract the two fractions:

1751/136 - 448/136 = (1751 - 448)/136 = 1303/136

We can simplify this fraction by finding a common factor to divide both the numerator and denominator. Since both 1303 and 136 are relatively prime, we cannot simplify it any further. Therefore, the final answer is:

12 7/8 - 56/17 = 1303/136

A circle in the xy-plane has a diameter with endpoints (2,4) and (2,14). An equation of this circle is (x-2)^2+(y-9)^2=r^2 ,where r is a positive constant. What is the value of r?

The center of the circle is the midpoint of the diameter, which is at (2, (4+14)/2) = (2, 9). We can substitute this center point into the equation of the circle to get:

(x - 2)^2 + (y - 9)^2 = r^2

(2 - 2)^2 + (9 - 9)^2 = r^2

0 + 0 = r^2

So we see that r = 0. Therefore, the equation of the circle is just:

(x - 2)^2 + (y - 9)^2 = 0

This describes a single point in the xy-plane, which is the center of the circle. Note that this point is already on the given diameter, so it makes sense that the radius is zero.

which number has which number has the lowest value? 1/6 1/3 - 1/9 1/3 - 1/6 1/4 - 1/6the lowest value?

To compare these fractions, we can first find a common denominator for all of them. The least common multiple of 2, 3, and 4 is 12, so we can rewrite the fractions with this denominator:

1/6 = 2/12

1/3 - 1/9 = (3/12) - (1/12) = 2/12

1/3 - 1/6 = (2/6) - (1/6) = 1/6

1/4 - 1/6 = (3/12) - (2/12) = 1/12

So the fractions can be ordered as follows, from least to greatest:

1/12 < 1/6 < 2/12 = 1/3 - 1/9 < 1/3 - 1/6

Therefore, the fraction with the lowest value is 1/12.

Patrick left home at 4:20 p.m. on Sunday. He returned 36.3 hours later. what day and time was it when he got home?

Answers

If Patrick left home at 4:20 p.m. on Sunday and returned 36.3 hours later, we can add 36.3 hours to the time he left to find the time he arrived home.

First, we need to convert 36.3 hours into days and hours. Since there are 24 hours in a day, we can divide 36.3 by 24 to get the number of days, and take the remainder to get the number of hours:

36.3 hours ÷ 24 hours/day = 1 day and 12.3 hours

So, Patrick returned 1 day and 12.3 hours later.

Adding 12.3 hours to the time he left at 4:20 p.m. on Sunday, we get:

4:20 p.m. + 12.3 hours = 4:20 p.m. + 12 hours + 0.3 hours
= 4:20 a.m. on Tuesday

Therefore, Patrick arrived home at 4:20 a.m. on Tuesday.

Answer: 4 o'clock am on Tuesday

Step-by-step explanation: 4pm on Sunday+36 hours which gets you to Monday 4 pm + 12 hours= 4 am on Tuesday.

What is the image of (−12,−12) after a dilation by a scale factor of 1 4​ centered at the origin?

Answers

the image of point (-12, -12) after a dilation by a scale factor of 1/4 centered at the origin is (-3, -3).

How to find?

To find the image of point (-12, -12) after a dilation by a scale factor of 1/4 centered at the origin, we can use the following formula:

(x', y') = (kx, ky)

where (x, y) are the coordinates of the original point, (x', y') are the coordinates of the image after dilation, and k is the scale factor.

In this case, the scale factor is 1/4 and the center of dilation is the origin (0, 0). Therefore, we have:

x' = (1/4) × (-12) = -3

y' = (1/4) × (-12) = -3

So the image of point (-12, -12) after a dilation by a scale factor of 1/4 centered at the origin is (-3, -3).

-12x + (-18y) = -48

c. 12x+6y= 10
-24x + (-6y) = -16

d. 12x+6y=10
-4x + (-6y) = -16

Answers

The correctly multiplied pair of equations that shows the system of equations by eliminating y first.

d. 12x+6y=10 and -4x + (-6y) = -16.

Explain about the method of elimination?

There are either two or three equations with two or three variables when there is a system of linear equations. In this session, we'll be dealing for both x and y while using a two-equation system.

To create an equation in one variable using the elimination approach, you can either add as well as subtract the equations.To eliminate a variable, add the equations when the coefficients about one variable are in opposition, and subtract the equations when the coefficients among one variable are in equality.

Given equation are:

12x + 6y = 10   ...eq 1

2x + 3y = 8   ...eq 2

To eliminate the y first, multiply eq 2 by -2.

-2(2x + 3y = 8)

-4x + (-6)y = -16   eq 3

On solving both eq1 and eq 3

8x = -6

x = -3/4

Thus, the correctly multiplied pair of equations that shows the system of equations by eliminating y first.

d. 12x+6y=10 and -4x + (-6y) = -16.

Which model best represents the relationship between time and volume?
OA linear model would best represent the relationship because scatterplot A is fairly linear.
O An exponential model would best represent the relationship because scatterplot B is fairly linear.
A power model would best represent the relationship because scatterplot C is fairly linear.
A linear model would best represent the relationship because scatterplot C is fairly linear.

Answers

The answer is C: A power model would best represent the relationship because scatterplot C is fairly linear.

What is a power model?

In this the rate of change of the dependent variable is proportional to the power of the independent variable. In other words, when the independent variable increases, the dependent variable increases at a rate that is proportional to the power of the independent variable. This type of model is often used to describe phenomena such as population growth, economic growth, and physical processes such as diffusion.

When looking at the graph of scatterplot C, it is clear that the relationship between time and volume follows a power model.

The data points in the graph are fairly linear, meaning that as the log of time increases, the log of volume increases at a rate that is proportional to the power of the log of time.

This indicates that a power model would best represent the relationship between time and volume, making C the correct answer.
